Need help to figure out what I am doing wrong. The first picture shows my Multisim circuit. I set the VP to 1 and
change the frequency as shown in the table. I measured the Vout P-P. I then used 20 log(Vout / Vin) to get the dB. All these are shown in the table on the picture. My problem is that the very next page of the instructions ask me to do a graph of the frequency response of the filter. As shown in the second picture, the dB’s start at -12 and ascend to 0. My calculations in the table go from -7.89 dB up to 11.91 dB. Something is not right. Should I not have gotten any dB measurements above 0? And if that is the case, what did I do wrong in my calculations?
